Question $6[10]$a$)$ The evolution of CPUs has led to integrated circuits of higher and higher density in the pursuit ofspeed. However, as clock speed and logic density increase, a number of physical obstacles $($heatgeneration$,$ increased delays due to resistance and capacitance, memory latency$)$ become moresignificant. Thus, other approaches in CPU organization and architecture are needed to improveperformance. Briefly describe the following techniques built into modern processors designed toimprove CPU performance:i$.$ Pipelining: $(2)$ii$.$ Branch prediction: $(2)$iii$.$ Data flow analysis: $(2)$iv$.$ Speculative execution: $(2)$v$.$ Multicore organization: $(2)$
